Summary of human population surveys in Richard Toll and Lac de Guiers, and Barkedji and Linguère, in 2016 and 2017–18, including Bayesian estimation of prevalence of urinary and intestinal schistosomiasis. Median Schistosoma eggs per mL of urine is given as an indicator of infection intensity. Children were aged 5–17 years and adults aged 18–78 years. BCI=Bayesian credible interval.
